4.5.6 Dynamics Section Control Summary
The following tables show the parameters used by each different section of the Dynamics
Section. The first line of each table shows the function, the second line shows the front panel
designation on the 601, the third shows the parameter name, and the fourth shows the
parameter's range.

4.5.7 Additional Dynamics Parameters
In addition to the previously mentioned controls, there are several additional parameters
affecting the dynamics processor (Dynamic filtering, compressor and AGC). None of these
controls are accessible directly from the front panel, however they may be accessed via MIDI or
by means of the realtime editor (refer to Appendix A). If you modify any of these parameters and
get lost, you can return to some semblance of reality by either loading program 256 and
starting over or by loading any other program. Many of the preset programs modify these
parameters also; this means that you can’t simply duplicate a program by re-entering its front
panel parameters.
